Re: 8.1l 1500?

I'd do a 6.0L (much better mid and top end power) swap, unless you are planning on towing something very heavy lots. The tranny and rear diff of the 1500 would grenade pretty quickly with the monster low end torque of the 8.1L. Even the power of the 6L will put lots of stress on the drivetrain components, but would be manageable with small upgrades. the 1500SS has a upgraded tranny (4L65E) over the standard 1500 (4L60E). If you decide to do the 8.1 I would def. upgrade to a 4L80E or a well built 4L60. If Im correct the 6.0L is almost a drop in replacement.
